Bitcoin is really hard to own this time
Why, what's the reason.?
Until whenever you can have Bitcoin as long as there is value. You can buy any amount of Bitcoin and whenever you want as long as you have the money. It's very simple, nothing is difficult as long as you have some money.
but if i hold my bitcoin from 2017 till today maybe i have it or maybe i already get it during the bull run and change it into fiat for some reason.
Unfortunately it's just a dream that has not come true. Start acting, don't just have fun fantasizing without giving you any benefit. You have to get into the market immediately for several reasons too, it's never too late as long as there is a desire. Bitcoin is still a promising long-term investment, immediately do something that makes you stop daydreaming.
